Nanovision UM-720F V2 (7" USB Touchscreen Display, VESA)
| 11.03.2011 I've bought several of these and they are great. I managed to group up to 5 of these along with 2x 55" LED screens on a single PC. The only thing is that, once in a while, Windows XP or some applications do updates and very often all the screen set is messed up. Sometimes, the USB screens also "loose connection" with the PC. Decent support on these seem hard to find.
